Why do they already have three releases of maps with 2013? I could understand forward dating maybe one release from now for the holidays, but three? Also, how often do they update? quarterly? --- This torrent worked fine, just renamed to "gmapprom.img", and threw it on the 2gb internal storage. Using some old 2011 tz and basemap. I also like how you got your nickname to display on the map version info. Very slick.

Instructions for those having difficulty. This is very simple. I have been doing this since 2009 for the North America map.

1. Format your 2gb SD card to FAT or FAT32 (this is the card in your device - you need it because the IMG map is 1.5gb)
2. Create a folder on the memory card called “Garmin”
3. Copy the downloaded IMG file into the Garmin folder on your SD card.
4. Make sure the IMG file is named “gmapsupp.img” on the SD card.
That's it.

I have a Garmin 1450. I d/led this torrent, then renamed the North American map file "gmappprom.img" and--via USB cable--replaced the old "gmapprom.img" file, which was only visible to me by accessing G:.System in the Explore bar. This didn't work--when I turned on the Nuvi, it said 'no map data found'! Afterward, I made sure I switched the "gmapprom.img" file I was using from a .rar file to an .img, but still I had no luck.

So that worked. The downside is that the unzipped North American map was too big for my 1450, so I had to use the Canadian one instead. Is the only way to remedy this by using an SD card? I've already deleted superfluous voice files. And if I use an SD card, do I need an SD card reader on my comp? I've literally never used SD anything before haha.

Instruction:
Download the torrent.
Download WinRar
Open the North America file with WinRar and you will see a file name (gmapsupp.img).
take a empty SdCard and create a folder named (Garmin)
Put the file into the (Garmin) folder.
Then put the SdCard to your garmin Gps and your done!

The DL says 2013.20 after download. In the Nuvi it says it's 2013.10. Maybe I DLed Ipmark's other torrent ( I don't think so) but it still says 2013.10 in the machine. I thought this would save hours of DL time but if you update to a clone (micro SD) it takes minutes.
